Media Multitasking Scale (MMS) has been used to assess this phenomenon, but it is yet to be validated for a Portuguese population. This study analysed the validity of a Portuguese Version of the MMS (n = 171 Portuguese adolescents) based on inter-item correlations and confirmatory factor analysis. The results suggest changes in the original version to reflect more recent digital media tendencies for a better fit to the Portuguese adolescents\u2019 sample. Additionally, results showed that Multitasking with Media and Non-Media and Concentration Without Multitasking were partially predictors of mental health problems (predictive validity), highlighting the scale\u2019s utility in assessing media multitasking behaviours and their impact on psychological well-being.<\/jats:p>","DOI":"10.3390\/socsci14030187","type":"journal-article","created":{"date-parts":[[2025,3,19]],"date-time":"2025-03-19T09:18:26Z","timestamp":1742375906000},"page":"187","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Media Multitasking Scale: Validation Study with Portuguese Adolescents"],"prefix":"10.3390","volume":"14","author":[{"given":"Lu\u00edsa","family":"Campos","sequence":"first","affiliation":[{"name":"Faculty of Education and Psychology, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"},{"name":"Research Centre for Human Development, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-6592-7795","authenticated-orcid":false,"given":"B\u00e1rbara","family":"Nobre","sequence":"additional","affiliation":[{"name":"Faculty of Education and Psychology, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"},{"name":"Research Centre for Human Development, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9881-3514","authenticated-orcid":false,"given":"Catarina","family":"Morais","sequence":"additional","affiliation":[{"name":"Faculty of Education and Psychology, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"},{"name":"Research Centre for Human Development, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6725-4043","authenticated-orcid":false,"given":"Lurdes","family":"Ver\u00edssimo","sequence":"additional","affiliation":[{"name":"Faculty of Education and Psychology, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"},{"name":"Research Centre for Human Development, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1936-5363","authenticated-orcid":false,"given":"Pedro","family":"Dias","sequence":"additional","affiliation":[{"name":"Research Centre for Human Development, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"},{"name":"Department of Psychology, University of the Azores, 9500-321 Ponta Delgada, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4700-1927","authenticated-orcid":false,"given":"Jiutong","family":"Luo","sequence":"additional","affiliation":[{"name":"Faculty of Education, Shenzhen University, No. 3688 Nanhai Road, Shenzhen 518060, China"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,19]]},"reference":[{"key":"ref_1","unstructured":"Achenbach, Thomas M., McConaughy, Stephanie H., Ivanova, Masha Y., and Rescorla, Leslie A.
